Fine. In principal I've nothing against typing || for double bars
(even though people moving from TeX/LaTeX probably will be used to |
for one bar and \| for two bars). Some questions:

* Can one expect to get the right (that is the same as \Vert gives)
spacing by typing || (two bars) in ConTeXt in the future?
* Sometimes one would like to write absoulte value of z times absolute
value of w, i.e. |z| times |w|. What if one writes |z||w|, will the
double bar in the middle be equivalent to \Vert? (That is not wanted)
* Will it be possible to write \Bigl|| and \Bigr|| to scale both bars
to other sizes?
* What if one would like to have three bars with the same spacing
between the bars as in \Vert?
